Instance (computer science) When a computer system creates a new context based on a pre-existing model or scheme, the model is said to have been instantiated. The encapsulated context that results from this instantiation process is referred to as an instance of the model or scheme. This general concept applies specifically across computer ...
SAS (software) SAS (previously " Statistical Analysis System ") [1] is a statistical software suite developed by SAS Institute for data management, advanced analytics, multivariate analysis, business intelligence, criminal investigation, [2] and predictive analytics. SAS' analytical software is built upon artificial intelligence and utilizes ...
The field has evolved due to the convergence of multiple technologies, including ubiquitous computing, commodity sensors, and increasingly powerful embedded systems, as well as machine learning. [9] Older fields of embedded systems, wireless sensor networks, control systems, automation (including home and building automation ), independently and collectively enable the Internet of things. [10 ...
Offset (computer science) In computer science, an offset within an array or other data structure object is an integer indicating the distance (displacement) between the beginning of the object and a given element or point, presumably within the same object. [1] : 100–103 The concept of a distance is valid only if all elements of the object ...
Computer virus. Hex dump of the Brain virus, generally regarded as the first computer virus for the IBM Personal Computer (IBM PC) and compatibles. A computer virus [1] is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs.
In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). [1] [2] SQL injection must exploit a security vulnerability in an application's software, for example, when user ...
A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware. Classical physics cannot explain the operation of these quantum devices, and a scalable quantum computer could perform some calculations exponentially faster than ...
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages. Programmers typically use high-level programming ...
